Specification forming part of Let-ters Potent No, l', dated January 20, 18GB.

To all whom it may concern:

Be it known that l, RioHARD Neuro-N An LEN, of Cleveland, in the county of Cuyahoga and State of Chio, have inviited neur and use- `ful' Improvements in Barrels and Casks for Storing and-Transporting Oil, 85e.; and I do igurel is a lperspective view, und Fig. 2

is alongtuinal section.

` .The nature `of my invention relates to a cylindrical cask or barrel composed ofsh ect metal and wooden lags or staveslitting its exterior cylindrical surface-and `hound with hoops, leaving the metallic ends exposed, in oneof which, near the margin, is fixed a compound i'netellic bung, tap-hole, and 'vent-pipe, the saine being secured for storage or transportation by means of a, screw-cap and gasket, in the manner hereinafter speciiied,tho whole structure being a new 'article of manufacture.

-i cui aware that oil-casks 'of Various forms `have o-cn constructed by having lthe interior composed of shcetinctal and the exterior of stares or wooden lags hound on by hoops or otherwise. I shallthereforeleyno claim to this feature of the construction, but to my speciai arrangement and conibinution'of parts, es .full-y set 'forth in the following speciiicef,`

tion and claim. .I-first take sheet metal (gat vanized sheet-iron, for example) and foi'ntit into a cylinder, as shown in vertical' section A, Fig. 2.- Thc edges are united by a clasp.-

'joinn or lapped and riveted, and either sol .dcred with soft solder or .bra/.cd,.in order tol make the joint perfectly tight. I then c ut tiro disks, B, ofthe suine' kind of inicial, n diamcter about one inch or less greater than the infv side o fthe' cylinder.' .The margin' of these disksor heads are turned at right angles, the'A lip ,thus formed being just large enough tojllseen in Fig; l) The cap D being removed, a.

thc'borc ol the cylinder', to the ends of which they arc'sccurcd by rivets or by a clasp-Joint, es seen in1`i;. 2, and then furtherv secured by sol't soldcrin'qr or bracing, so as to innkc' them perfectly tight. In one ol' the heads,

before inserting it into a cylinder, l. securel n l combined bung, Atup-hole, and vcntl as sccn at 0 Fig, 2.. '.lhis compound bnngholc consists of a heavy inctaliic ring, .with a circular iange upon the inside, which projects about hnlf un inch around the opening in the head made to receive it, and this circular Bange is brazcd or soldered to the head upon the inside. This compound hung and tap-hole projects about half an inch outside of the head, and isprovided with a screw-thread on the outside, up-

has a gasket of sheet-lead or other soft substance impervious to oil, to insure perfect tightness when the cap is screwed on. The bung and tap-hole is situated upon the lower margin of the head when the vessel lies in a, horizontal position, leaving a space above the bung-hole in the ring C suficientiy large to introduce thel vent-pipe iti. This vent-pipe consists of a small metallic pipe having a here of one-tenth of an inch or less. end of the pipe E is soldered into the bung C,

the pipe turns at right angles und' follows up -the inside' of the head B to the upper portion of the interior of the cash, as seen in lig..2, thus forming' n communication between the interior or" the cask and the external air when thecep D is off, but which .communication is closed when the oop D is screwed on. The ingsor staves F are suiicient in number to cover'the external surface of the cylinder, to which they areclosely fitted, being thicker in the ,middle and thinner -atie-ach end, to insure the binding of 'the hoops G,by which they are 'held in place.. The outside of the cylinder being smooth, with no iianges or prostave, ior the heads are not'c'overed with wood. In iilingthc vessel. it is placed. on end, as

i'unnci can bc introduced into the bung-hole a and the lierrci filled with oil, the confined air escaping thri'fsgh thc vcntpipe E.
